Vegetative compatibility and phenotypic characterization as a means of determining genetic diversity of Aspergillus flavus isolates
(University of Nairobi, 2018)
oxigenic Aspergillus species produce mycotoxins that are carcinogenic, hepatotoxic and teratogenic immunosuppressing agents in both human and animals. Kenya frequently experiences outbreaks of aflatoxicosis with the worst ...
Electrophoretic Deposition And Characterization Of TiO2/Nb2O5 Composite Thin Films For Dye Sensitized Solar Cells
(University of Nairobi, 2018)
In this study, Electrophoretic Deposition (EPD) technique was used to fabricate TiO2/Nb2O5 composite
thin films on FTO coated glass for application as photoelectrodes in Dye Sensitized Solar Cells (DSSC). A
TiO2/Nb2O5 ...
Isoflavones and Rotenoids from the Leaves of Millettia oblata ssp. teitensis
(University of Nairobi, 2017)
: A new isoflavone, 8-prenylmilldrone (1), and four
new rotenoids, oblarotenoids A−D (2−5), along with nine known
compounds (6−14), were isolated from the CH2Cl2/CH3OH
(1:1) extract of the leaves of Millettia oblata ...
Naphthalene Derivatives from the Roots of Pentas parvifolia and Pentas bussei
(University of Nairobi, 2016)
The phytochemical investigation of the CH2Cl2/MeOH (1:1) extract of the roots of Pentas parvifolia led to the isolation of three new naphthalenes, parvinaphthols A (1), B (2), and C (3), two known anthraquinones, and five ...
A Multi-dimensional Model for Determining Susceptibility to Unintentional Insider Threats: the Case of Social Engineering Through Phishing
(University of Nairobi, 2019)
Many of the information security incidents that make headlines around the
world are perpetrated by authorized users of the information systems. These users are
commonly referred to as insiders. The Unintentional Insider ...
Device Simulation of Sb2S3 Solar Cells by SCAPS-1D Software
(University of Nairobi, 2019)
Antimony sulphide (Sb2S3) has drawn research interest due to its promising properties for photovoltaic applications. The progress in developing highly efficient Sb2S3 solar cells has stimulated this study to a great extent. ...
A Neoarchean paleomagnetic pole from the Kisii Series of western Kenya: Implications for crustal mobility
(University of Nairobi, 2016)
The Kisii Series lavas of western Kenya were the target of a paleomagnetic study. The Kisii Series is a volcano-sedimentary sequence dated to 2531 ± 3 Ma (U–Pb) that rests unconformably over the Mesoarchean–Neoarchean ...
On Analysis And Synthesis Operators And Characterization Of The Synthesis Matrix Of A Frame In Terms Of The Frame Operator
(University of Nairobi, 2018)
In this research paper we introduce the operators associated with a frame. That is the Analysis
and the Synthesis Operators and their basic properties. The structure of matrix representation
of the Synthesis operator is ...
Near Real-time Tropospheric Water Vapour Profiling Using A Ground-based GPS Receiver
(University of Nairobi, 2017)
This article presents a remote-sensing tool employing an artificial neural networks algorithm for near real-time determination of the relative humidity (RH) profile above a site using global positioning system (GPS) data ...
Investigation of flow dynamics of porous clinkers in a ball mill using technitium-99m as a radiotracer.
(University of Nairobi, 2019)
A radiotracer investigation was carried out in a ball mill of a cement plant in Kenya. Residence time distribution (RTD) of raw feed to the mill was measured using Technetium-99m adsorbed on the clinkers as a radiotracer. ...
